Key Features & Advantages
  • Unparalleled 300+ mAh/g Energy Barrier: Engineered upon an advanced lithium-manganese oxide layered-spinel integrated matrix, unlocking an elite specific discharge capacity of ≥300 mAh/g at a 4.8V cutoff to push active cells past traditional energy limits.
  • Pristine Crystallographic Crystalline Phase: Rigid synthesis firing rules eliminate stray phase formations, producing a pure crystalline signature with completely clean XRD spectra to protect repeatable lab data.
  • Optimized Micro-Nano Secondary Compaction: Spherical particle framing provides a high compaction density (≥2.65 g/cm³), guaranteeing superior active material volume distribution and ideal slurry behavior during blade coating.

APPLICATION SCOPE: Premium positive electrode active powder perfectly optimized for high-energy density pouch cells, solid-state configurations, and next-generation lithium battery research protocols.
PACKAGING: Hermetically packaged in premium multi-layer aluminum-plastic film vacuum seal structures to protect the pristine crystalline boundary during global logistics transit.
IMPORTANT NOTICE: Owing to the unique atomic structural coordination of lithium rich manganese based cathode materials, this compound must be warehoused away from ambient moisture (≤500 ppm baseline). Unseal and manipulate batches strictly within an anhydrous, high-purity inert glovebox environment to successfully address how to prevent lmr moisture degradation prior to thermal cycling.

Frequently Asked Technical Questions

Why is ATOMFAIR® 300 mAh/g Lithium-Rich Manganese-Based Cathode Powder preferred for high-energy cells?

ATOMFAIR® 300 mAh/g Lithium-Rich Manganese-Based Cathode Powder triggers an elite specific discharge capacity of ≥300 mAh/g when operating within a 2.0V–4.8V electrochemical window. This enables massive energy density gains compared to traditional nickel or cobalt alternatives.

What is the typical Initial Coulombic Efficiency (ICE) profile of this material?

Tested reliably via half-cell configurations at a current density of 25 mA/g across a broad 2.0V – 4.8V activation range, the powder demonstrates a premium initial coulombic efficiency baseline of 90.6%, minimizing early active lithium immobilization.

How does the micro-nano secondary particle morphology assist in slurry prep?

The spherical micro-nano secondary particle structuring centers around a balanced D50 granularity of 8.0 – 16.0 μm. This layout delivers a high powder compaction density of ≥2.65 g/cm³ and exceptional liquid wetting behavior without aggregate clotting.

How is the structural phase purity of this research-grade precursor batch validated?

Every distributed production run is subjected to standard X-ray diffraction mapping. The resulting spectra showcase zero impurity spikes, ensuring an uncompromised crystalline phase layout that yields highly stable room-temperature cycling retention ≥95% over 100 loops.

How to prevent lmr moisture degradation during warehouse handling?

To comprehensively solve how to prevent lmr moisture degradation, the compound arrives inside airtight vacuumed aluminum-plastic films. The batch should remain unsealed strictly within a high-purity argon gas glovebox environment (maintaining water levels below 500 ppm) before ink formulation.

This cathode material must be operated within the voltage window of 2.0V to 4.8V to achieve rated capacity. Extended cycling beyond 100 cycles may reduce capacity retention below 95%.

  • Voltage Window Constraint: Exceeding 4.8V can cause irreversible capacity fade and structural degradation.

How does the discharge capacity of the ATOMFAIR 300 mAh/g LMR cathode vary between 4.6V and 4.8V cutoff voltages at different C-rates?

At 0.1C, the material delivers ≥300 mAh/g at 2.0-4.8V and ≥280 mAh/g at 2.0-4.6V, while at 1.0C, capacity is ≥245 mAh/g at 2.0-4.8V and ≥220 mAh/g at 2.0-4.6V. This performance trade-off shows that extending the upper cutoff voltage to 4.8V yields higher specific capacity at the cost of increased oxidative stress on the electrolyte and cathode interface.

What critical powder characteristics must be accounted for during slurry preparation and electrode coating for this LMR cathode material?

The slurry pH of 10.5–11.5 and moisture content <500 ppm require controlled humidity environments and solvent selection to avoid gelation or degradation of binder systems. The D50 particle size of 8.0–16.0 μm and tap density ≥1.60 g/cm³ are compatible with standard slot-die or doctor-blade coating processes, but the alkaline nature may necessitate NMP-based PVDF binders to maintain slurry stability.

What storage conditions are recommended to preserve the electrochemical performance of this lithium-rich cathode powder?

The powder must be stored in sealed, dry containers under inert atmosphere to maintain moisture below 500 ppm as specified, since higher moisture levels can trigger parasitic side reactions and capacity fade. Its alkaline pH of 10.5–11.5 also requires protection from atmospheric CO2 to prevent carbonate formation, which would alter the active surface chemistry and degrade initial coulombic efficiency.

This lithium-rich manganese-based cathode powder delivers a specific capacity exceeding 300 mAh/g at 2.0–4.8V, with 95% capacity retention over 100 cycles, making it a strong candidate for high-energy-density cell development. However, its ultra-high voltage window demands electrolyte systems stable beyond 4.6V, and its alkaline slurry pH (10.5–11.5) necessitates strict moisture control during handling and electrode fabrication.

Positive

  • Ultra-high specific capacity: Achieves ≥300 mAh/g at 0.1C in a 2.0–4.8V window, enabling cell-level energy densities beyond conventional NMC or LCO cathodes.
  • Excellent cycle retention: Retains ≥95% capacity after 100 cycles at room temperature with 0.1C baseline, indicating good structural stability under moderate cycling conditions.

Trade-offs

  • High-voltage electrolyte demand: Operation up to 4.8V requires electrolyte formulations with anodic stability beyond conventional carbonate solvents to prevent oxidative decomposition.
  • Moisture and pH sensitivity: Slurry pH of 10.5–11.5 and specified moisture content <500 ppm indicate strong alkalinity and hygroscopicity, requiring dry-room or glovebox processing to avoid hydrolysis and gelation.
